Similar numerals of reference are employed to indicate correspondingpart-sin the several figures.

Referring to the drawings; the numeral 1 designates the saw frame ofsuitable form of construction and comprising side, end, and cross bars,or beams, as will be more fully hereinafter referred to from time totime in I describing the support of the several parts of the mechanismthereon, and said frame is also provided with an extension 2, projectingoutward from a portion of one side thereof. On the said frame is mountedthe sawunandrel 3, which extends across the frame '1 and has the endsthereof journaled in adjustable boxes 4, whereby the same may be kept intrue line together with the parts supported thereby. On said mandrel 3is keyed a friction disk 5, and on the end of the mandrel adjacent tothe outer portion of one of the side bars thereof is mounted a circularsaw 6, of any preferred form of construction, and which may be suppliedwith the incidental mechanism now commonly employed in connection withcircular saws. A small friction wheel 7 is also mounted on the mandrel3, between the disk 5 and the saw 6, and at a suitable pointintermediate of latter parts. In the extension 2 of the frame 1, and onthe upper surface thereof is mounted atransverse shaft 8, which hasbearing in adjustable boxes 9, and

is formed with a key seat 10, the ends of the said shaft 8 being formedwith eccentrics 11. On the shaft 8 is mounted a belt pulley 12, andadjacent to the belt pulley is a friction wheel 13, adapted to engagewith the disk 5, which is provided with a suitable key adapted to engagethe key seat and have adjustable movement on the shaft 8 longitudinallythereof by means of a flanged collar 14, engaged by a yoke carried bythe upper end of a lever 16, whose lower end 17 embraces a rod 18. Onthe rod 18 at opposite sides of the lower embracing end 17v of the lever16 are situated collars 19, to hold said end in position and throughwhich end the said rod 18 has free movement. The said rod 18 is formedwith grooves or key seats 20 and 21, to be engaged by the keys of theseveral parts on the said rod. At the opposite ends of the extension 2,arms 22 are mounted on the rod 18, and have a series of openings 23therein, to which is adapted to be adjustably secured the lower ends ofconnecting rods 24, whose upper ends are attached to arms 25 ofeccentric rings 26, which embrace the eccentrics 11 on the shaft 8, thesaid arms 25 being in like manner provided with a series of openings 27for the adjustment of the upper ends of the connecting rods 24.

By the mechanism set forth, including the adjustable boxes 9, thefriction wheel 13 is brought into bearing contact with the face of thedisk 5, or said wheel 13 is disconnected from the disk 5, as may befound necessary boxes 28 secured to the under side of the extension 2,and connected to said boxes are recessed guards 29, which are adapted toengage the lower portions of the arms 22, to hold the same in properposition when the rod 18 is adjusted, and said lower embracing ends ofthe arms 22 are provided with suitable keys engaging the grooves or keyseats and 21, by means of which the rotary motion imparted to the rod 18is transmitted through the arms 22, and the parts connected thereto tothe eccentrics 11, as heretofore stated. The rod 18 extends outwardparallel with the adjacent side of the frame 1, and passes through a boxsecured adjacent to the end of said frame, and the free end of the rodhas an operating lever 31 connected thereto and by means of which thesaid rod 18 may be either revolved or rotated, or shiftedlongitudinally, and when the said rod 18 is shifted sufliciently thefriction Wheel 13 may be adjusted on the shaft 18, so as to bring thesame to bear against the side of the disk 5 opposite to that shown inFig. 1, in order to reverse the motion of the saw 6 if desired.

Under the frame 1 is mounted an axle or shaft 32 having bearing in anadjustable box 33 having guide flanges 34 thereon and a slot 35 in theupper flange through which projects a bar or rod 36 connected at itslower end to' said box 33 and at its upper end to a lever 37 having adog engaging a toothed sector 38. The opposite end of the said shaft 32is held in a pivoted box 34 as fully shown in Fig. 9, which consists ofa flanged plate 40 having set screws 41 projecting through oppositeflanges thereof and bearing against the said box to permit raising andlowering of the end of the shaft in connection with the box 33.. On thefree end of said shaft 32 is mounted a pinion 42 which meshes with therack 43 of the carriage 44, and a large friction wheel 45 is alsomounted on said shaft and is adapted.

to have its rim thrown out of and into gear with the friction wheel 7 onthe saw mandrel 3 at one side, and to transmit motion from said wheel toa friction wheel 46 having bearing in boxes 47 in the free end of anelbow lever 48 mounted on a shaft or axle 49 located adjacent to one endof the frame 1, said lever being formed with an operating handle 50supplied with a dog 51 adapted to engage a toothed segment 52 secured onsaid frame adjacent to the shaft or axle 49. The shaft or axle 49 isformed with a key seat or groove 49 on which is adjustably mounted avertically situated bevel gear 53 which is adapted to mesh with asmaller horizontally mounted bevel gear 54, keyed to the lower end of aVertically disposed mandrel 55, having a key groove or seat 56,extending throughout the length thereof. Another friction wheel 56is'permanently keyed to the axle or shaft 49 and is adapted to beengaged by the wheel 46 to impart motion to said shaft or axle. Thelower end of said mandrel is stepped in a box 57 mounted in a baseextension 58 of an upright 59 also having a horizontal top arm 60 inwhich the upper end of the said mandrel is journaled. The shaft or axle49 bears in a box 60 in an extension 61 of the base extension 58, asfully shown in Fig. 4, and in this figure the hub of the gear 53 isshown on the shaft or axle 49, the remaining portion of the said gearnot being illustrated.

The opposite portion of the base extension 58 immovably in engagementwith the log.

On the mandrel 55 are adjustably mounted a multiplicity of horizontallydisposed edging vsaws 67 having grooved collars 68 in connectiontherewith and loosely embraced by yokes ,69 carried on the ends oflevers 70 and by means of which the saws may be vertically adjusted orraised and lowered for purpose of setting same at points of elevationdesired. .To one side of the upright 59 is secured a ratchet bar 71 insuch manner as to leave a slot 72 through which the levers 70 pass, and3 the latter are provided with dogs 73 adapted j to engage the saidratchet bar 71 to hold the saws 67 in their adjusted positions. Adjacentto said ratchet bar 71 and adj ustably secured to the side of theupright is a scale plate or strip 74 and in connection with each lever70 is an index 75 adapted to be relatively positioned adjacent to oragainst said scale plate or strip in order to readily accomplish andascertain the necessary or required amount of adjustment of the saws 67.The lower portion of one side of the base extension 58 of the upright 59is also provided with a grip or hand hold 76 to conveniently adjust thesaid upright and the parts carried thereby. The carriage 44 has wheels76 running on tracks 77 and is adapted to be moved back and forthadjacent to the saw 6, and therein is mounted a log turning device,shown more clearly in Fig. 5, and comprises a curved arm 78, providedwith spurs or spikes 79 on the upper 'edge thereof and is free to moveupward or downward through an opening and against a guide 81 and islimited in its downward movement by resting on a pin 81 on a standard95. A groove 82 is formed in one side of said arm and is adapted to beengaged by a pin 83 in "connection with the guide 81, to steady themovement of the arm as will be readily seen.

'mounted in the said groove 84. The pin 85 is also connected to theupper curved extension of a rack bar 89 and to the adjacent end of thearm 78 and forms a pivot for the latter;

and the said rack bar 89 is adapted to be thrown into engagement with agear 90 mounted on a shaft 91 by an eccentric 92 bearing against theunder side of the same and having an operating handle or grip 93. As therack bar 89 is operated to move in the direction of the arrow, shown inFig. 10, it draws backward on the pin 85, which separates the arm 87from the support 88 and raises the same causing the spikes thereof totake firmly into the under side of the log and raise the latter andgradually turn it over, when the said arm 87 shall have reached the rearlimit of its movement, and bring the log against the arm 78, which,during said operation of the other parts, will have been graduallyrising as shown in dotted lines, and assist the carrier in overturningthe log to bring the uncut side thereof in proper position to the saw 6.When the log shall have been properly turned, themovement of the rackbar 89 is reversed and the same is caused to return to its normalposition as shown in full lines and dragging the log over with it to beagain sawed.

It willbe understood that there will be more than one of the log turningdevices set forth mounted on the carriage in order to equalize themovement of the log throughout its length.

The guide 81 has a rack 94 on the under side thereof which meshescontinuously with the gear 90 and is simultaneously moved with the otherparts of the log turning devices, and

connected to and moving with said guide is standard 95, so it will beseen that the logs may be moved or shoved toward the edge of thecarriage adjacent to the saw 6 when turning of the same is not desired,and this independent movement is accomplished through the medium of thepivotal mounting of one end of the rack bar 89, which, when not raisedby the eccentric 92 is disengaged from the gear 90.

The shaft 91 extends along the carriage and is formed with key-seats orgrooves 96 in the same to permit parts which will be presently referredto to be slid or moved longitudinally thereon. Friction mechanism and acompound or double acting ratchet are mounted on the carriage for movingthe standards and for operating the log turning mechanism heretofore setforth. This mechanism is intermediately situated between two standardsin order to simultaneously operate the same, or if more standards andlog turning mechanisms be employed a single arrangement of suchmechanism could be employed to operate the whole as will be readilyunderstood and would constitute no departure from the invention andmechanism shown as it would require merely an elongation of the shaft 91and the employment of an additional number of grooves 96. The saidmechanism comprises a frame or support 98 on the carriage having twoboxes 99 in which the shaft 91 is longitudinally and rotatingly movable.On the the outer side of each of the. boxes 99 is located a coiledspring 100 which has one end secured to said boxes and the other end tothe shaft 91 and surrounds the said shaft. It will be understood thatthe said shaft 91 is longitudinally adjustable in order to connect theseveral gears carried thereby and by the adjacent mechanism. Vv'hen thesaid shaft is rotated to move the standards 95, the springs 100 windthereon and when the operating mechanism is released from said shaft,the said springs automatically rotate the shaft in the oppositedirection and return the standards to their normal positions. Asheretofore stated, to the carriage 44 are secured a series of travelingwheels 76 moving on tracks 77, and one of said wheels is constructed andarranged as a friction wheel which is adapted to be intermittentlyengaged by a friction wheel 103 adjustably journaled in a box 104carried by the free lower end of a lever 105 journaled on a transverseshaft 106 mounted in a bracket 107 rising from the frame or support 44,and said lever extends upward a proper distance for convenientengagement and operation. On the outer end of said shaft 106 is fixed afriction wheel 107 which is adapted to bear against the friction wheel103 whenever the latter is moved to engage the wheel 7 6 aforesaid, andthe degree of rigidity or firmness of contact of said friction wheels103 and 107 is made regulable by the power applied to the lever 105 andalsoby the movable or adjustable mounting of said wheel 103 inconnection with the lever. On the inner end of the shaft 106 is mounteda bevel gear 108 which is adapted to be thrown into mesh with a similargear 109 mounted on the shaft 91 and is longitudinally movable, beingheld in engagement with the gear 108 by a spring 110 bearingthereagainst and secured to a collar 111 on the said shaft 91. Thismovement of the gear 109 is necessary in view of the automatic movementof the said shaft 91. The gear 109 meshes with a similar gear 112mounted on another transverse shaft 113 having bearing in suitable boxesin the central portion of cross bars of a double arched frame 114. Onthe said shaft 113 is fixedly mounted a large ratchet wheel 115 whichhas combined therewith an annular gear 116, and on said shaft is alsoloosely mounted a combined ratchet andgear 117 and with the latter andthe annular gear 116 meshes a pinion 118 carried by a short shaft 119having bearing in the frame 114 and having acrank 120 thereon in orderto operate the log turning mechanism by hand if so desired. Over theratchet wheels 115 and 117 is mounted a lever 121 having a forked end122 loosely journaled on the shaft 113 and carrying reversely operatingpawls 123 and 124, pivoted thereto and engaging said ratchet wheels. Itwill be seen that the operation of said lever 121 in either directionwill cause a continuous rotation of the shaft 113 in one direction whichis owing to the connection between the pinion 118 engaging the combinedratchet and gear 117 and the annular gear 116 of ratchet Wheel 115. .Astop pawl 125 is also employed in connection with the ratchet Wheel 115to prevent back movement therewith and suitably secured to the archedframe 11 1, and on the lever 121 is a stop 126 adapted to bear on thetop of the said frame and to contact with pins 127 adjustably mounted inopenings in said frame to limit the throw of the said lever. It will beunderstood that the pawls on the lever 121 will each alternately andreversely slip in one direction and operate in the reverse direction.

It will be seen that the speed of the saw and the carriage are regulatedto each other by the mechanism set forth and that some of the parts areautomatic in their action; further that the log turning and feedmechanisms may be operated either by the double ratchet, the frictionmechanism in connection with shaft 91, or by hand as fully set forth.The several parts are combined for unitary operation, and a great savingof labor, time and expense is consequent by the use of the device as awhole, heretofore fully set forth.
